Absolutely terrific colonial American corkscrew. Business end is very magnetic hand forged iron. In general design it is crude but it has some very attractive ridges and rings and a nice central bulge which is very nicely beveled. Certainly made by a blacksmith with some skill. The handle is hollowed bone with some groove work on the sides and to a lesser degree in the center. A minor degree of chipping on the edges but nothing disfiguring or even unexpected in a piece with this age...
